Introducing Basement Watchdog BW4000 Combination Sump Pump

The basement watchdog bw4000 combination pump includes a powerful 1/2HP AC powered primary pump which is connected to a battery back-up system.

Unlike other combo pumps, it has placed the back-up pump midway within the construction of the main pump. Also, the design makes sure that the discharges of the two pumps merge at the top of the housing. This unique design helps the pump to create a small footprint.

Problems You Might Have To Face

Buying a sump pump is a long term investment. That’s why we like to inform you about all the troubles you may need to deal with.

The pump may not start running

This complaint is pretty common. Sometimes it can happen due to a locked impeller. When debris or small pebbles get stuck into the impeller and prevent it from rotating, all you have to do is, clean the impeller properly.

But the reason can be something else too like, a defective float switch, defective pump, or poor power source. Then you have to find the cause and replace the defective parts.

Buying the right batteries

Though the package includes a battery box, you have to buy the battery separately. Now, it’s important to buy the right battery. Without it, the back-up system won’t operate.

The 30HDC140S basement watchdog back-up pump battery is highly recommended. It may last 1 to 3 years. Otherwise, you can use any major sump pump battery or marine deep cycle battery. But make sure the battery is not maintenance-free.

The pump may shut down too frequently

Now you don’t want your pump to shut down when you need it the most. This problem can occur due to water flowing back from the pipe or defective float switch. To solve this problem, you have to replace the check valves or the float switch.

Abnormal sound or vibration

Many people think their pump is damaged when they hear abnormal sounds or vibration. But sometimes your pump has nothing to do with such sounds. It may occur due to a broken check valve or a broken screen intake.

Basement Watchdog Review: Features And Benefits

Here is the most awaited section of this basement watchdog review. Keep reading:

Cast iron housing

The material used for pump housing is cast iron. Cast iron is considered the most durable material for a sump pump. It has great heat-dissipating elements that help to keep the pump cooler. It also has anti-corrosive properties that protect the outer layer of the pump in the water.

The pump is reliable. It can surely pass the test of time.

½ HP AC powered pump with a back-up

This pump includes a 1/2HP AC powered pump that has a flow rate of 3200 GPH at 10’ head. But the biggest advantage is its battery-powered backup pump. It pumps 1730 GPH at 10’ head.

When the power is cut and the main pump stops working, the back-up system kicks in. It has enough power to handle a medium water level.

Moreover, when the electricity is not gone but the primary pump faces a hard time due to heavy water inflow, the back-up system becomes a helping hand. With two powerful pumps working, you have nothing to worry about.

Polycarbonate impeller

Since this pump has to pump a large amount of water inflow, the impeller has to be sturdy enough. Luckily, this pump features a polycarbonate impeller.

Polycarbonate is one of the strongest materials for impellers. It is close to unbreakable. It takes the abuse of large debris and pebbles easily.

Besides, the material has some degree of thermal insulation. That means it is perfect for commercial use also.

Effective dual switch

A switch is the most crucial element of a sump pump. It detects or calculates the level of water. When the water level crosses a predetermined level, it sends a signal to the pump. Thus the pump knows when to work.

This pump features dual reed switches for better performance and peace of mind. One switch is placed a little lower than the other one. In case one switch fails when touched by the water, the water level rises and touches the other one. Then the 2nd one sends a signal to the pump.

LED Monitoring System

The LED monitoring system enables it to let you know the exact problem. The manual describes how you can identify the problem just by looking at the lights.

Additional Features

  • It has a computer-controlled automatic charging system. The charging status is always on the check. The computer will supply a pre-programmed amount of power when the battery status is low.
  • It also comes with an audible alarm system. When the control unit detects that only ½ hour of pumping power is left, the alarm starts ringing. You can silence the alarm during emergencies if you want. But the warning lights will remain until the issue is solved.
  • It offers you a 2-year manufacturer warranty. But keep in mind that. Only the pump is replaceable during the warranty period.
  • A descriptive and user-friendly instruction manual is another cool feature.

Wrapping UP

Basement Watchdog BW4000 has made it possible for you to buy just one pump and leave all the worries behind. It will take care of your house even during a power cut. Though the price is not the cheapest, it will surely cost you more to buy two pumps independently.

Besides, this pump is equipped with quite useful features that you can only expect from a reliable manufacturer.

After all of this being said, the question is, would you give it a chance to prove its potential?

Hope you benefited from this basement watchdog review.

Here are some tips for you. Have a look:

  • Check the battery fluid level once every four months.
  • Do not use the power cord to carry the pump. It may cause severe damage.
  • Do not use this pump in the pits handling sewage water, saltwater, or hazardous liquid. It can only handle groundwater.
  • You should drill a 1/8” hole in the elbow of the pump to prevent airlock in the system.
